UNICORN Binance Local Depth Cache

Description | Installation | How To | Documentation | Examples | Change Log | Wiki | Social | Notifications | Bugs | Contributing | Commercial Support

A local Binance DepthCache Manager for Python that supports multiple depth caches in one instance in a easy, fast, flexible, robust and fully-featured way.

Part of 'UNICORN Binance Suite'.

Create a local depth cache of Binance with just 3 lines of code:

import unicorn_binance_local_depth_cache

ubldc = unicorn_binance_local_depth_cache.BinanceLocalDepthCacheManager(exchange="binance.com")
ubldc.create_depth_cache("LUNABTC")

And get the depth with:

asks = ubldc.get_asks("LUNABTC")
bids = ubldc.get_bids("LUNABTC")

Catch an exception, if the cache is out of sync while accessing its data:

try:
    print(f"Top 10 asks: {ubldc.get_asks(market=market)[:10]}")
    print(f"Top 10 bids: {ubldc.get_bids(market=market)[:10]}")
except DepthCacheOutOfSync as error_msg:
    print(f"ERROR: {error_msg}")

Stop and delete a single depth cache:

ubldc.stop_depth_cache("LUNABTC")

Stop the full instance:

ubldc.stop_manager_with_all_depth_caches

Get the right logger:

logging.getLogger("unicorn_binance_local_depth_cache")

Discover more possibilities.
